OIL-LEVEL-INDICATING ATTACHMENT SFOR,y CRANK CASES. I 1,V

Application filed March 25, 1921.

To all whom t may concern.'

Be it known that I, ALEXIS F. GILLET, a vcitizen of the United States, residing at Gmaha, in the county of Douglas and State ot Nebraska, have invented certain new and useful Improvements in Oil-Level-lndicating Attachments for Crank Cases, of which The invention has tor 'its ob] supply of oil in the engine crank case of an automobile. is to provide a tubular container which will communicate with the ,bottom ot the crank case and may be disposed approximately in a vertical position, so thatV the indicating-rod may accurately register-the depth ot theoil and may extend to a level lcorresponding to the lowermost part of the crank case. Another object is to provide such a construction that the indicating-rod may be accessible for conveniently ascertaining the supplyT of oil'in the crank case. Still another object is to provide an attachment for the purpose -described which may be practically'manufacturedV and may readily be mounted upon an automobile by any person oit ordinary skill.

In the accompanying drawing which illustrates the invention, Fig. 1 is a broken, side view of an indicating-rod. Fig. 2 is an end view of the engine crank case with the oil-level indicating attachment applied thereto, a part of the body of an automobile being shown in transverse section. Fig. 3 is a broken, side view ot the rectilinear part of the L-shaped, tubular container and its mounting in the floor of an automobile. Fig. l shows a portion of the bottom of the crank case and a T pipecoupling connection therewith for a part of the L-shaped, tubular container.

Referring now to the drawing for a more particular description, the invention is shown and described in connection withl the body -l of an automobile including a floor 5, the crank case for the engine being indicated at 6.

The indicator to be described is particularly designed for use upon the Ford type of automobiles. The engine crank case for these automobiles is provided, to extend below its bottom, with a boss 7 for a threaded mounting therein of a screw -plug (not shown) to permit drainage as occasion may A ect, broadly, to provide a means for ascertaining thef One of the specific objectsthe floor 5.

require. It will be understood that oil is placed in the crank case sufficient in quantity to till it to a certain, limited depth for lubricating the engine, and toavoid van eX- cess or an inadequate supply of oil testcocks 8 and 9 have been used to determine the depth of the oil, these being mounted in the end of thev crank case, and since these test-cocks are' not readily accessible, their use isvinconvenient and impracztical;`

In. order that the supply of oil may be conveniently ascertained I provide a tubular container A approximately of L-shape, supported by and extending downwardly from Numeral 10 indicates an apertured cup having a flange 11, said cup and its flange being disposed in an aperture 12 having a recess 13 opening thereon, said aperture and 'recess being formed in the floor. The rectilinear, upright part .14 of the L-shaped container is adapted to be inserted in the aperture 15 of the cup and is provided lwithav collar 16 adapted to be disposed in the cup to rest on the bottom thereof, and which operates to sustain the the horizontal part 17 of said container being connected at one of its ends with a T pipe-coupling 18 which is mounted in the threaded aperture of the `boss 7, its opposite end being threaded in an elbow pipe-coupling 19 in which the lower end of the upright part 1K1- is also threaded.

It will thus be seen that the L-shaped container communicates with the bottom of the crank case, and that its horizontal part 17 and the distal end ot the upright part 14 are disposed lower than the lowest level of the crank case, and since the oil in the upright part 14 will be at the same level as the oil in the crank case, it may be measured, and the depth of oil in the latter may be determined by use of an indicatingrod 20.

The rod 20, adjacent to its lower end, is provided with suitable indicating characters 21,these being disposed in spaced relation, longitudinally of the rod. It is provided at its upper end with a disc 22 having a lesser diameter than the diameter of the cup and operating as a handle, and when the rod is disposed in the upright part 14E ot the container, the disc will engage the upper end thereof and will be disposed in the plane of the tlange 11, and on account so weight ot the'container A or a part, thereof,

dicator, it may be stated that, since the.V

part 1,4 ot the container A is` maintained in, approximately, a vertical position, the

oilon the rod 2O willcorrectly indicate the` depthof. oil in the crank case; also the fact that the rectilinear. part 149 extends downwardly a distance'equal to or beyond the plane of the crank case, is obviously an advantage to permit measurement. ofthe oil. It there is an excess of oilit may be drawn oil by use of'one of the cocks 8 or 9,

and-if there is a: deiiciency, additional oil.

may be supplied to the'crank case. It will be noted that the testsimay` be made by an operator while within the automobile, which is a feature of convenience; and since the discv or handle 22 of the rod 2O does not project above the surface of: the floor it will not be obtrusive and will not be disturbed by occupants of the automobile.

It will be seen that the device may be readily appliedto an automobile. The aperture 12 being first `formed in the floor 5` and the pipe-coupling 18 and elbow 19 being mounted on the part 17, said coupling 18` may be mounted in the threaded' boss the upright part 11i may then be inserted in the aperture 15 of the cup 10 and threaded in the elbow 19; and it is obvious that the device will not interfere with complete drainage of the crank caseV since said member 18 is provided with a screw-plug x which may be removed for cleaning out the crank case.

I claim:

In an oil indicating` attachment for the crank case of a vehicle havinga iloor' provided with an aperture, a pipe coupling threaded in the crank case, an apertured cup provided.with a flangev and adapted to be disposedin the aperturer of. the floor, a tubular container including a horizontal part communicating with thepipe coupling and'y a vertical part adapted. to loosely engage in the aperture of the cup and connecting` with said horizontal part and having a colla-r adapted to bear upon the upper surface of the bottom of said cup for a support of said-tubular container, andv an indicating rod provided with a handle and adapted to be inserted in the vertical part of the tubular container with its handle normally disposedv in the cup in line with the flange. thereof.

InA testimony whereof, l have aiiixed my signature in presence of two witnesses.
